Here is a brief excerpt about friction from wikipedia:
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts work to heat). This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is converted to thermal energy whenever motion with friction occurs, for example when a viscous fluid is stirred. Another important consequence of many types of friction can be wear, which may lead to performance degradation and/or damage to components.
The poster of the video had this reply:
True. But the friction is very low. The motion of the water drops approximates the frictionless condition very well.
We hope you like the video and check out more cool physics videos. Have you ever seen anything like this? Comment with your ideas on this and even if these surfaces could be used in cool applications.
They should try and apply the frictionless sphere and use the same tactics to make a windshield for cars and then it would be easier to drive in the rain because the water wouldn’t stay on the window it would fall right off not to mention that the windshield wipers would work so much better without the friction
FRICTIONLESS SPHERE… Have fun driving an opaque bubble car!
Like water off a duck’s back.
Freeze Point. A friction-free zone where the asserting and opposing forces are in equilibrium. 33.33333333333. 45.00000000000. SYNCHRONISATION. All movement have a Freeze Point.
What- And no one understands this???????
Uh…what? This is surprising for what reason?
I know- I do this while I’m pissing on something. You wanna do something!!!! A slow moving sphere in a larger faster moving sphere. And a fraction away- a sphere moving at incredible speeds—- then try to enter it.
Oh click saver hero, where art thou?
I’m just interested in the “frictionless” sphere. Just think of all of the possibilities when you can ignore such a basic law of physics! I would make the soles of my shoes frictionless so I can just fart and glide my$#%&!@*home after a long day of work.
What is supposed to happen ? .
Earth’s flat
Very cool, but Clark Griswold did this back in 1989.
